Description

i DK 172182 B1in DK 172182 B1

Den foreliggende opfindelse angår en rygeartikel, f.eks. i form af cigaretter og lignende rygeartikler.The present invention relates to a smoking article, e.g. in the form of cigarettes and similar smoking items.

Der findes en række forslag til tilvejebringelse af ciga-5 retter, der udviser lav afgivelse af sidestrømsrøgkompo-nenter. Således beskrives i GB patentskrift nr. 2 094 130 A cigaretter omfattende cigaretpapir med luftpermeabili-teter ved viskos strømning på højest 3 Coresta-enheder og Do/t-forhold på 0,08-0,65 cm/s, hvor Do betyder diffusi-10 onskoefficienten for oxygen gennem nitrogen i papir, og t betyder tykkelsen af cigaretpapiret, der udviser lave afgivelser af totalt partikelformigt materiale, vand og ni-cotinfrit materiale (PMVNF) samt nicotin i sidestrømsrøgen.There are a number of suggestions for providing ciga-5 dishes that exhibit low emission of sidestream smoke components. Thus, GB patent specification 2,094,130A discloses cigarettes comprising cigarette papers with air permeability at viscous flow of no more than 3 Coresta units and Do / t ratios of 0.08-0.65 cm / s, where Do means diffusion. 10 indicates the coefficient of oxygen through nitrogen in paper, and t means the thickness of the cigarette paper exhibiting low releases of total particulate matter, water and nicotine-free material (PMVNF) as well as nicotine in the sidestream smoke.

En anden metode til tilvejebringelse af lav afgivelse af komponenter i cigaretters sidestrømsrøg består i anvendelse af cigaretpapir omfattende en eller flere side-strømsreducerende forbindelser. I GB patentskrift nr.Another method of providing low emission components of cigarette sidestream smoke consists of the use of cigarette paper comprising one or more side-current reducing compounds. In GB patent specification no.

20 2 139 869 A beskrives cigaretpapir indeholdende en eller flere forbindelser fra gruppen bestående af lithiumhydro-xid, aluminiumhydroxid, calciumhydroxid, kaliumformiat, natriumformiat og natriumacetat. Det totale partikelfor-mige materiale i sidestrømsrøg hidrørende fra cigaretter 25 omfattende papir af denne art er reduceret med mindst 30 %, sammenlignet med en tilsvarende cigaret omfattende gængs cigaretpapir. Et andet eksempel på anvendelse af sidestrømsreducerende forbindelser er givet i US patentskrift nr. 4 231 377, ifølge hvilket der inkorporeres en 30 kombination af magnesiumoxid og et salt i cigaretpapir.20 2 139 869 A discloses cigarette paper containing one or more compounds from the group consisting of lithium hydroxide, aluminum hydroxide, calcium hydroxide, potassium formate, sodium formate and sodium acetate. The total particulate matter in sidestream smoke resulting from cigarettes comprising paper of this kind is reduced by at least 30%, compared to a corresponding cigarette comprising conventional cigarette paper. Another example of the use of sidestream reducing compounds is given in U.S. Patent No. 4,231,377, which incorporates a combination of magnesium oxide and a salt in cigarette paper.

Den til grund for den foreliggende opfindelse liggende opgave går ud på at tilvejebringe cigaretter eller lignende rygeartikler med forbedret lav sidestrøm.The object of the present invention is to provide cigarettes or similar smoking articles with improved low side flow.

35 DK 172182 B1 235 DK 172182 B1 2

Denne opgave løses ifølge opfindelsen ved en rygeartikel omfattende en stav af rygemateriale omfattende rygemate-riale og et papiromslag omgivende dette, som er ejendommelig ved, at densiteten af rygematerialet i staven lig-5 ger i intervallet fra ca. 100 mg/cm3 til ca. 260 mg/cm3, at rygematerialet omfatter mindst ca. 20 vægt-% ekspanderet tobak, at omslaget omfatter et forbrændingsretarderingsmiddel, og at rygeartiklen ved rygning under stan-dardrygebetingelser i en rygemaskine giver mindst seks 10 sug.This object is solved according to the invention by a smoking article comprising a rod of smoking material comprising smoking material and a paper wrap around it, which is peculiar in that the density of the smoking material in the rod is in the range of from about. 100 mg / cm 3 to approx. 260 mg / cm3, that the smoking material comprises at least approx. 20% by weight of expanded tobacco, the wrapper comprising a combustion retardant and the smoking article when smoking under standard smoking conditions in a smoking machine gives at least six to 10 sucks.

Ved "standardrygebetingelser i en rygemaskine" forstås i denne forbindelse rygebetingelserne i en Coresta-stan-dardmaskine, i hvilken der tages et sug på 35 cm3 med 2 15 sekunders varighed hvert min.By "standard smoking conditions in a smoking machine" in this connection is meant the smoking conditions in a Coresta standard machine, in which a vacuum of 35 cm3 is taken at a duration of 2 15 seconds every minute.

Rygeartiklerne ifølge opfindelsen giver fortrinsvis, ved rygning under standardrygebetingelser i en rygemaskine, et totaludbytte af sidestrøms-PMVNF, der ikke overstiger 20 ca. 17 mg pr. rygeartikel, mere foretrukket ikke over ca.The smoking articles of the invention preferably provide, when smoking under standard smoking conditions in a smoking machine, a total yield of sidestream PMVNF not exceeding about 20%. 17 mg per smoking article, more preferably not more than approx.

15 mg og især ikke over ca. 10 mg.15 mg and in particular not more than approx. 10 mg.

Rygeartiklerne ifølge opfindelsen udviser fortrinsvis, ved rygning under standardrygebetingelser i en rygemaski-25 ne, et totaludbytte af sidestrøms-carbonmonoxid (CO), der ikke overstiger ca. 35 mg, mere foretrukket ikke over ca.The smoking articles according to the invention preferably exhibit, when smoking under standard smoking conditions in a smoking machine, a total yield of sidestream carbon monoxide (CO) not exceeding approx. 35 mg, more preferably not more than ca.

30 mg og især ikke over ca. 20 mg.30 mg and in particular not more than approx. 20 mg.

Rygeartiklerne ifølge den foreliggende opfindelse udviser 30 fortrinsvis, ved rygning under standardrygebetingelser i en rygemaskine, et forbrug af rygemateriale i perioderne mellem sugene, der ikke overstiger 50 % af det totale forbrug af rygemateriale, dvs. det samlede forbrug af rygemateriale i perioderne mellem sugene og under sugene.The smoking articles according to the present invention preferably exhibit, when smoking under standard smoking conditions in a smoking machine, a consumption of smoking material during the periods between sucks not exceeding 50% of the total consumption of smoking material, ie. the total consumption of smoking material during the periods between suction and suction.

35 Særligt foretrukket overstiger forbruget af materiale i perioderne mellem sugene ikke ca. 40 % af det totale for- DK 172182 B1 3 brug af rygemateriale, og især ikke over ca. 30 % af det totale forbrug af rygemateriale.35 Especially preferably, the consumption of material during the periods between suction does not exceed approx. 40% of the total use of smoking material, and in particular not more than approx. 30% of the total consumption of smoking material.

Det rygemateriale i rygeartiklerne ifølge opfindelsen, 5 som ikke er ekspanderet tobak, omfatter fortrinsvis bladtobak, passende i gængs skåren fyldstofform. Bladtobakken kan foreligge som plade- og/eller stængeltobak. Det rygemateriale, der ikke er ekspanderet tobak, kan omfatte en rekonstitueret tobak eller en tobakserstatning.The smoking material in the smoking articles according to the invention, which is not expanded tobacco, preferably comprises leaf tobacco, suitably in commonly cut filler form. The leaf tobacco may be available as plate and / or stem tobacco. The non-expanded tobacco smoking material may include a reconstituted tobacco or a tobacco substitute.

1010

Den ekspanderede tobak kan være plade- og/eller stængel-tobak. Den ekspanderede tobak er fortrinsvis en pladetobak, som er fremkommet ved en tobaksekspanderingsproces, ved hvilken der tilvejebringes en høj ekspansionsgrad.The expanded tobacco may be plate and / or stem tobacco. The expanded tobacco is preferably a sheet tobacco produced by a tobacco expansion process which provides a high degree of expansion.

15 Højekspansionsprocesser er f.eks. beskrevet i beskrivelserne til US patentskrift Re nr. 30 693 samt i GB patentskrift nr. 1 570 270 og 2 160 408 A. Ved anvendelse af højekspansionsprocesser kan der opnås tobaksekspansionsværdier, udtrykt ved forøgelsen af fyldværdien, påfra 20 typisk ca. 75 % og endog op til ca. 125 %. Tobak, der har været underkastet en højekspansionsproces, kan have en densitet på f.eks. fra 100 mg/cm3 til ca. 175 mg/cm3, målt under anvendelse af et Borgwaldt-densimeter.15 High expansion processes are e.g. disclosed in the descriptions of U.S. Patent Re No. 30,693 and in GB Patent Nos. 1,570,270 and 2,160,408 A. Using high-expansion processes, tobacco expansion values, expressed by increasing the fill value, can be obtained from typically about 20%. 75% and even up to approx. 125%. Tobacco that has been subjected to a high expansion process can have a density of e.g. from 100 mg / cm 3 to approx. 175 mg / cm3, measured using a Borgwaldt densimeter.

25 Andelen af ekspanderet tobak i rygematerialet er fortrinsvis mindst ca. 30 vægt-%.The proportion of expanded tobacco in the smoking material is preferably at least approx. 30% by weight.

Dersom ekspansionen af den ekspanderede tobak er af en lav størrelsesorden, kan det som bekendt være nødvendigt, 30 at andelen af den ekspanderede tobak i rygematerialet nærmer sig eller antager værdien 100 %.If the expansion of the expanded tobacco is of a low order of magnitude, it may be necessary to know that the proportion of the expanded tobacco in the smoking material approaches or assumes the value 100%.

Udtrykket "forbrændingsretarderingsmiddel" anvendes i denne sammenhæng til betegnelse af en forbindelse, der 35 ved inkorporering i eller på et papiromslag til en stav af rygemateriale giver en reduktion af ulmehastigheden DK 172182 B1 4 for den rygende materialestav. Det skal bemærkes, at "forbrændingsretarderingsmiddel" såvel refererer til anvendelse af to eller flere sådanne forbindelser som til anvendelse af en enkelt forbindelse. På tale som forbin-5 delser, der kan anvendes som forbrændingsretarderingsmidler, alene eller i kombination, kommer aluminiumammonium-sulfat, diammoniumhydrogenorthophosphat, ammoniumdihydro-genorthophosphat og natriumdihydrogenorthophosphat. På tale som andre forbindelser, der kan anvendes som for-10 brændingsretarderingsmidler ifølge opfindelsen, kommer borsyre, aluminiumborat, calciumborat, ammoniumbromid, lithiumbromid, magnesiumbromid, ammoniumchlorid, magnesi-umchlorid, zinkchlorid, aluminiumphosphat, calciumphos-phat, kaliumsilicat, aluminiumsulfat, calciumsulfat, mag-15 nesiumsulfat og natriumcarbonat.The term "combustion retardant" is used in this context to mean a compound which, by incorporating into or onto a paper cover into a smoking material rod, reduces the smelling rate DK 172182 B1 4 for the smoking material rod. It should be noted that "combustion retardant" refers to the use of two or more such compounds as well as to the use of a single compound. Speaking as compounds which can be used as combustion retardants, alone or in combination, come aluminum ammonium sulfate, diammonium hydrogen orthophosphate, ammonium dihydrogen orthophosphate and sodium dihydrogen orthophosphate. Speaking as other compounds which can be used as combustion retardants according to the invention come boric acid, aluminum borate, calcium borate, ammonium bromide, lithium bromide, magnesium bromide, ammonium chloride, magnesium chloride, zinc chloride, aluminum phosphate, calcium phosphate, calcium phosphate, calcium phosphate, calcium phosphate, calcium phosphate magnesium sulfate and sodium carbonate.

Når der anvendes vandopløselige forbindelser som forbrændingsretarderingsmidler, påføres disse fortrinsvis omslagspapiret i vandig opløsning. Hvis en som forbræn-20 dingsretarderingsmiddel anvendt forbindelse ikke er vandopløselig, tilsættes den fortrinsvis i pulverform som et fyldstof til papirpulpen under papirfremstillingsprocessen. Vandopløselige forbrændingsretarderingsmidler kan tilsættes papir, således at det tilsatte materiale for-25 trinsvis ikke overstiger ca. 20 %. Vanduopløselige forbrændingsretarderingsmidler kan foreligge i en mængde på op til ca. 30 %.When water-soluble compounds are used as combustion retardants, these are preferably applied to the wrapping paper in aqueous solution. If a compound used as a combustion retardant is not water-soluble, it is preferably added in powder form as a filler to the paper pulp during the papermaking process. Water-soluble combustion retardants may be added to paper so that the added material preferably does not exceed approx. 20%. Water-insoluble combustion retardants may be present in an amount of up to approx. 30%.

Foruden en eller flere forbindelser, der fungerer som 30 forbrændingsretarderingsmiddel, kan det i de her omhandlede rygeartikler anvendte omslagspapir indeholde et si-destrømsreducerende fyldstof, f.eks. aluminumhydroxid, lithiumhydroxid eller magnesiumhydroxid.In addition to one or more compounds which act as a combustion retardant, the wrapping paper used in the smoking articles herein may contain a side-current reducing filler, e.g. aluminum hydroxide, lithium hydroxide or magnesium hydroxide.

Luftpermeabiliteten af det i rygeartiklerne ifølge opfindelsen anvendte omslagspapir overstiger fortrinsvis ikke ca. 20 Coresta-enheder.The air permeability of the wrapping paper used in the smoking articles according to the invention preferably does not exceed approx. 20 Coresta units.

5 Luftpermeabiliteten af et papir, udtrykt i Coresta-enheder, er den mængde luft, i cm3, der passerer gennem 1 cm2 papir på 1 min under en konstant trykdifferens på 1,0 kPa.5 The air permeability of a paper, expressed in Coresta units, is the amount of air, in cm3, passing through 1 cm2 paper in 1 minute under a constant pressure difference of 1.0 kPa.

10 Cigaretpapir består af et sammenvævet net af fibre, der sædvanligvis hovedsageligt eller praktisk taget fuldstændigt består af cellulosefibre med mellemliggende partikler af et fyldstof, såsom calciumcarbonat. Åbningerne i fiber/fyldstof-matrixen har en bredde på ca. 1 pm, og 15 denne dimension er lille sammenlignet med tykkelsen af papiret (almindeligvis 20-50 pm). Luftstrømningen gennem sådanne åbninger bestemmes af viskositetskræfter. Når papiret derimod er perforeret efter papirfremstillingsprocessen, er perforeringerne relativt store, almindeligvis 20 med breddedimensioner af samme størrelsesordenen som papirtykkelsen, og i dette tilfælde er luftstrømningen gennem perforeringerne bestemt af inertikræfter.Cigarette paper consists of an interwoven web of fibers, usually or mainly consisting entirely of cellulose fibers with intermediate particles of a filler such as calcium carbonate. The openings in the fiber / filler matrix have a width of approx. This dimension is small compared to the thickness of the paper (usually 20-50 µm). The air flow through such openings is determined by viscosity forces. On the other hand, when the paper is perforated after the papermaking process, the perforations are relatively large, usually 20 with width dimensions of the same order of thickness as the paper thickness, and in this case the air flow through the perforations is determined by inertia forces.

Når permeabiliteten af et perforeret papir bestemmes ved 25 Coresta-permeabilitetsbestemmelsesmetoden, skal det bemærkes, at den målte permeabilitetsværdi omfatter summen af permeabiliteten hidrørende fra viskos strømning gennem de åbninger, der hidrører fra selve papirfremstillingsprocessen, og permeabiliteten hidrørende fra inertistrøm-30 ningen gennem perforeringerne. Et papir vil ogsåudvise de samme to permeabilitetskomponenter, hvis papiret ikke er perforeret, men foruden de små huller med viskos strømning udviser større huller med inertistrømning, som i det følgende betegnes "punkturhuller". Papir med den sidst 35 omtalte opbygning kan f.eks. fremkomme ved mangelfuld papirfremstillingsteknik .When the permeability of a perforated paper is determined by the Coresta permeability determination method, it should be noted that the measured permeability value comprises the sum of the viscosity flow permeability through the apertures resulting from the papermaking process itself and the perert flow permeability permeability. A paper will also exhibit the same two permeability components if the paper is not perforated, but in addition to the small holes with viscous flow, larger holes exhibit inertial flow, hereinafter referred to as "puncture holes". Paper with the last 35 mentioned structure can e.g. appear by defective papermaking technique.

DK 172182 B1 6DK 172182 B1 6

Den totale luftstrømning gennem et papir kan udtrykkes: Q = ZAP = Z'A(P)n hvor 5 Q er luftstrømningen (cm3/min) A er arealet (cm2) af papir gennemstrømmet med luft 10 P er trykdifferensen over papiret (kPa) Z er permeabiliteten af papiret hidrørende fra viskos strømning gennem de fra papirfremstillingsprocessen hidrørende åbninger i Coresta-15 enheder (cm/min/kPa) Z' er permeabiliteten af papiret hidrørende fra strømning gennem perforeringer og/eller punktur-huller (cm/min/kPa) og 20 n er en konstant for en given mængde perforations- eller punkturhuller, hvor 0,5 s n < 1,0, hvor den eksakte værdi af n afhænger af størrelsen af perforations- eller punkturhullerne.The total air flow through a paper can be expressed: Q = ZAP = Z'A (P) n where 5 Q is the air flow (cm3 / min) A is the area (cm2) of paper flowed with air 10 P is the pressure difference over the paper (kPa) Z 'is the permeability of the paper resulting from viscous flow through the openings resulting from the papermaking process in Coresta-15 units (cm / min / kPa) Z' is the permeability of the paper resulting from flow through perforations and / or puncture holes (cm / min / kPa) ) and 20 n is a constant for a given amount of perforation or puncture holes, where 0.5 sn <1.0, where the exact value of n depends on the size of the perforation or puncture holes.

2525

Den totale permeabilitet af et papir omfattende perforeringer og/eller punkturhuller er (Z + Z'), og de relative værdier af Z og Z' for et givet papir kan beregnes ved måling af luftstrømningen gennem papiret ved en række 30 trykdifferenser over papiret under anvendelse af numerisk regression for Q/P-data i ovenstående ligning under anvendelse af en værdi for n, der stemmer med middelstørrelsen af perforeringerne/punkturhullerne i papiret.The total permeability of a paper comprising perforations and / or puncture holes is (Z + Z ') and the relative values of Z and Z' for a given paper can be calculated by measuring the air flow through the paper at a range of 30 pressure differences over the paper using of numerical regression for Q / P data in the above equation using a value for n that corresponds to the mean size of the perforations / puncture holes in the paper.

35 Det skal bemærkes, at den værdi på 20 Coresta-enheder, der er angivet ovenfor i forbindelse med omslaget til ry- DK 172182 B1 7 geartikler ifølge den her omhandlede opfindelse, refererer til permeabiliteten af omslaget hidrørende fra viskos strømning. Det fremgår således, at et omslag til en ryge-artikel ifølge opfindelsen kan have en total permeabili-5 tet, dvs. en permeabilitet bestemt under anvendelse af Coresta-permeabilitetsbestemmelsesmetoden, der overstiger 20 Coresta-enheder, nemlig hvis omslaget omfatter perforeringer og/eller punkturhuller.It should be noted that the value of 20 Coresta units set forth above in connection with the wrapping of stainless steel articles according to the present invention refers to the permeability of the coating resulting from viscous flow. It is thus apparent that a cover for a smoking article according to the invention may have a total permeability, ie. a permeability determined using the Coresta permeability determination method exceeding 20 Coresta units, namely if the cover comprises perforations and / or puncture holes.

10 Længden af stavene af rygemateriale i rygeartiklerne ifølge opfindelsen er fortrinsvis mindst 45 mm og fortrinsvis mindst 60 mm. Stavene har fortrinsvis ensartet tværsnit og samme dimension over hele stavens længde.The length of the rods of smoking material in the smoking articles according to the invention is preferably at least 45 mm and preferably at least 60 mm. The rods preferably have uniform cross-section and the same dimension over the entire length of the rod.

Hvis en stav af rygemateriale i en rygeartikel ifølge op- 15 findelsen har ensartet cirkulært tværsnit, hvilket almindeligvis er tilfældet, når der er tale om cigaretter og lignende rygeartikler, kan stavens periferi ligge i intervallet fra 10 mm til 30 mm. Medens der kan opnås betydelige og kommercielt nyttige fordele ved en reduktion af 20 sidestrømsrøgen for rygeartikler ifølge opfindelsen, når stavperiferien er 25 ± 5 mm, opnås exceptionelle fordele, når stavperiferien ligger under intervallet 25 ± 5 mm og ned til 10 mm. Stavperiferien af rygeartikler ifølge opfindelsen er fortrinsvis ikke mindre end 12,5 mm.If a smoking material rod in a smoking article according to the invention has a uniform circular cross-section, as is usually the case in the case of cigarettes and similar smoking articles, the periphery of the rod may range from 10 mm to 30 mm. While significant and commercially useful benefits can be obtained by reducing the 20 sidestream smoke for smoking articles of the invention when the bar periphery is 25 ± 5 mm, exceptional benefits are obtained when the bar periphery is below the range 25 ± 5 mm and down to 10 mm. The rod periphery of smoking articles according to the invention is preferably not less than 12.5 mm.

2525

Rygeartiklerne ifølge opfindelsen giver ved rygning under standardrygebetingelser i en rygemaskine fortrinsvis ikke mindre end 7 sug og mere foretrukket ikke mindre end 8 sug.The smoking articles of the invention, when smoking under standard smoking conditions in a smoking machine, preferably provide not less than 7 sugars and more preferably not less than 8 sugars.

3030

Rygeartiklerne ifølge opfindelsen omfatter fortrinsvis filtre eller mundstykker, der er fastgjort til staven af rygemateriale ved dennes ene ende.The smoking articles of the invention preferably comprise filters or nozzles attached to the rod of smoking material at one end thereof.

35 Rygeartiklerne ifølge opfindelsen kan omfatte ventilationsorganer.The smoking articles of the invention may comprise ventilation means.

DK 172182 B1 8DK 172182 B1 8

Ved fremstillingen af rygeartiklerne ifølge opfindelsen kan man anvende andet papir til omslaget end gængs papir.In the manufacture of the smoking articles according to the invention, paper other than conventional paper can be used for the cover.

Man kan f.eks. anvende et ark af rekonstitueret tobaksmateriale.One can, for example. use a sheet of reconstituted tobacco material.

5 I det følgende illustreres opfindelsen nærmere ved en række eksempler.In the following, the invention is further illustrated by a number of examples.

Opfindelsen illustreres endvidere nærmere ved hjælp af 10 tegningen, hvor fig. 1 viser en cigaret med et delvis afviklet mundstykkepapir, 15 fig. 2 skematisk viser et apparat anvendt ved bestemmelse af afgivelsen af sidestrømsrøgkomponener, og fig. 3-6 skematisk viser en del af det i fig. 2 viste apparat, idet fig. 4-6 viser den i fig. 3 viste del set i 20 retning af pilene A, B og C.The invention is further illustrated by means of the drawing, in which fig. 1 shows a cigarette with a partially unwound mouthpiece paper; FIG. 2 schematically shows an apparatus used in determining the output of sidestream smoke components; and FIG. 3-6 schematically show part of the embodiment of FIG. 2, FIG. 4-6 shows the embodiment of FIG. 3 in the direction of arrows A, B and C.

Eksempel IExample I

Der blev fremstillet en cigaret 1 ifølge opfindelsen om-25 fattende en cigaretstav 2 med en længde på 64 mm og en periferi på 24,82 mm samt et 20 mm langt celluloseacetat-fiber 3 fastgjort til staven 2 ved hjælp af et mundstykkeomslag 4. Staven 2 omfattede et tobakfyldstof 5, der udelukkende bestod af skåren pladetobak, indsvøbt i et 30 cigaretpapiromslag 6.

Ved simpel beregning ud fra de resultater, der blev opnået ved rygning af kontrolcigaretterne, ser man, at det forventede totale sidestrømsudbytte af PMVNF, TNA og CO for sammenlignelige cigaretter omfattende såvel det oven-35 for omtalte fyldstof omfattende 80 % DIET-ekspanderet tobak som et omslag af papir A, dvs. cigaretter af fjerde DK 172182 B1 12 type, beregnet på direkte lineær proportionalitetsbasis ville udgøre henholdsvis 14,9 mg, 3,0 mg og 33,4 mg pr. cigaret. F.eks. beregnes PMVNF-værdien som 24,5 (1-0,39) = 14,9, hvor 24,5 er PMVNF-værdien for kontrolcigaretten 5 af type 3 og 0,39 er PMVNF-værdien for kontrolcigaretten af type 1 minus den tilsvarende værdi for kontrolcigaretten af type 2 udtrykt som en brøkdel af værdien for de første kontrolcigaretter, dvs. PMVNF-reduktionsforholdet.By simple calculation based on the results obtained from smoking the control cigarettes, it is seen that the expected total sideways yield of PMVNF, TNA and CO for comparable cigarettes comprising both the above mentioned filler comprising 80% DIET expanded tobacco as well as a cover of paper A, i.e. cigarettes of the fourth type, calculated on a direct linear proportion basis, would amount to 14.9 mg, 3.0 mg and 33.4 mg per cigarette respectively. cigarette. Eg. the PMVNF value is calculated as 24.5 (1-0.39) = 14.9, where 24.5 is the PMVNF value for Type 3 control cigarette and 0.39 is the PMVNF value for Type 1 control cigarette minus the corresponding value of the type 2 control cigarette expressed as a fraction of the value of the first control cigarettes, i. PMWNF reduction ratio.

Som tidligere omtalt er de målte totale sidestrømsudbyt-10 ter af TNA og CO for cigaretter af fjerde type henholdsvis 2,25 mg og 31,6 mg. Man konstaterer således, at det gennemsnitlige totale sidestrømsudbytte af TNA for cigaretter af fjerde type, som er cigaretter ifølge opfindelsen, var 25 % mindre end den beregnede værdi. Tilsvarende 15 gav cigaretterne af fjerde type for CO en sidestrømsafgivelse, som var 6 % mindre end forudsagt. Cigaretterne ifølge opfindelsen udviste således en tydeligt synergis-tisk reduktionsvirkning for sidestrømsrøgkomponenterne.As previously discussed, the measured total sidestream yields of TNA and CO for fourth-type cigarettes are 2.25 mg and 31.6 mg, respectively. Thus, it is found that the average total sideways yield of TNA for fourth type cigarettes which are cigarettes of the invention was 25% less than the calculated value. Similarly, the fourth type of cigarettes for CO gave a sidestream emission that was 6% less than predicted. Thus, the cigarettes of the invention exhibited a distinct synergistic reduction effect for the sidestream smoke components.

Resultaterne af rygning af kontrolcigaretterne og cigaretterne ifølge opfindelsen af type 1 og 2 gennemført ved standardrygebetingelser i en rygemaskine er sammenstillet i tabel 3. Disse resultater viser, at medens cigaretterne 20 ifølge opfindelsen udviste et antal sug (sug nr.) svarende til antallet for kontrolcigaretterne, var udbytterne af sidestrømsrøgkomponenter for cigaretterne ifølge opfindelsen betydeligt reduceret sammenlignet med kontrolcigaretterne .The results of smoking the control cigarettes and cigarettes according to the invention of types 1 and 2 carried out under standard smoking conditions in a smoking machine are summarized in Table 3. These results show that while the cigarettes 20 according to the invention exhibited a number of sugars (suction no.) Corresponding to the number of the control cigarettes. , the yields of sidestream smoke components of the inventive cigarettes were significantly reduced compared to the control cigarettes.

For cigaretterne ifølge opfindelsen af type 1 var PMVNF således reduceret med 70 %. Det skal også bemærkes, at forholdet mellem den tobak, der blev forbrugt under ul-men, dvs. i perioderne mellem sugene, og den tobak, der 30 blev forbrugt under sugene, var betydeligt reduceret sammenlignet med kontrolcigaretterne.Thus, for the cigarettes of the invention of type 1, PMVNF was reduced by 70%. It should also be noted that the ratio of the tobacco consumed during the ulcer, ie. during the periods between the sugars and the tobacco consumed during the sugars was significantly reduced compared to the control cigarettes.

Målinger af tobaksforbruget under sugene og i perioderne mellem sugene blev foretaget under anvendelse af en for-35 brændingshastighedsmåler, der er nærmere beskrevet i Tobacco Patents information Bulletin, nr. 88/29-30, publi- 19 DK 172182 B1 ceret af N. & og D.J, Foster, Amberlea, North Road, Dib-den Purlieu, Southampton, S04 5PE, England.Measurements of tobacco consumption during suction and during the suction periods were made using a combustion rate meter, which is described in greater detail in Tobacco Patent Information Bulletin, No. 88 / 29-30, published by N. & and DJ, Foster, Amberlea, North Road, Dib-den Purlieu, Southampton, S04 5PE, England.

Det i fig. 2 viste apparat blev anvendt til bestemmelse af de ovenfor omtalte afgivelser af sidestrømsrøgkompo-nenter. Apparatet omfattede en Filtrona 302 lineær ryge-20 maskine 7 med en åbning, som er betegnet 8. Ved hver åbning af rygemaskinen 7 var der anbragt en lodretstående fiskehaleformet glasskorsten, hvor den, der er knyttet til åbningen 8, er betegnet med referencetallet 9. De i fig. 3 viste dimensioner a og b er henholdsvis 410 mm og 25 80 mm. Den i fig. 4 viste indre dimension (diameter) c er 24 mm og d er 22 mm. Anbragt på tværs over skorstenen 9 var en forud vejet Cambridge-filterplade 10. Til måling af røgkomponentafgivelsen i hovedstrømmen anvendtes en Cambridge-filterplade 10'. Den øvre side af filterplade 30 10 var via en slange 11 forbundet med en gasstrømningsmå ler 12, der med et rør 13 var forbundet til en gaspumpe 14. En infrarød carbonmonoxid-analysator med en (ikke vist) indre gascirkulationspumpe var forbundet til røret 13 med indgangs- og afgangsrør 15.The FIG. 2 was used to determine the above-mentioned releases of sidestream smoke components. The apparatus included a Filtrona 302 linear smoker 20 with an aperture designated 8. At each aperture of the smoker 7, a vertical fishtail shaped glass chimney was placed, the one associated with the aperture 8 being designated by reference numeral 9. The 3 and 4 are 410 mm and 80 mm respectively. The FIG. 4 is 24 mm and d is 22 mm. Located across the chimney 9 was a pre-weighed Cambridge filter plate 10. To measure the smoke component emission in the main stream, a Cambridge filter plate 10 'was used. The upper side of filter plate 30 10 was connected via a hose 11 to a gas flow meter 12 which was connected to a gas pump 14 by a pipe 13. An infrared carbon monoxide analyzer with a (not shown) internal gas circulation pump was connected to the pipe 13 with entry and exit pipes 15.

Ved drift af det i fig. 2 viste apparat til bestemmelse af afgivelsen af sidestrømsrøgkomponenter fra en cigaret 18, der ryges ved åbningen 8 i rygemaskinen 7, indstilles pumpen 14, således at der tilvejebringes en strømningsha-5 stighed gennem skorstenen 9, slangen 11 og røret 13 på 2,0 1 pr. min. Under rygningen af cigaretten 18 under standardrygebetingelser ved åbningen 8 går sidestrømsrøgen fra denne cigaret op i skorstenen 9 og hen til filtret 10. Den del af røgen, der ikke afsættes i filtret 10 10 eller på de indre vægge af skorstenen 9 går gennem rørene 11 og 13, og en delmængde af denne sendes gennem carbon-monoxid-analysatoren 17 via indgangs- og udgangsrørene 15 og 16.In operating the device shown in FIG. 2 to determine the discharge of sidestream smoke components from a cigarette 18 which is smoked at the opening 8 of the smoking machine 7, the pump 14 is set so as to provide a flow rate through the chimney 9, the hose 11 and the tube 13 of 2.0 per. mine. During the smoking of the cigarette 18 under standard smoking conditions at the opening 8, the sidestream smoke from this cigarette goes up into the chimney 9 and onto the filter 10. The part of the smoke which is not deposited in the filter 10 10 or on the inner walls of the chimney 9 passes through the pipes 11 and 13, and a subset thereof is passed through the carbon monoxide analyzer 17 via the input and output tubes 15 and 16.

15 Når rygningen af cigaretten 18 ved åbningen 8 og af to identiske cigaretter er tilendebragt, vejes filtret 10 påny. Fra den således bestemte vægt subtraheres den oprindelige vægt af filtret 10, hvorved man når frem til vægten af det totale partikelformige materiale (TPM), der 20 er afsat på filtret 10. Derefter blev filtret 10 extrahe-ret med et extraktionsopløsningsmiddel, f.eks. propan-2- ol. Den således fremkomne extrakt blev underkastet gaskromatografisk analyse til bestemmelse af de påfiltret 10 afsatte mængder af nicotin og vand. Summen af de således 25 bestemte mængder af nicotin og vand blev subtraheret fra den ovenfor omtalte gravimetrisk bestemte vægt af på filtret 10 afsatte TPM, hvorved man kommer frem til vægten af den på filtret afsatte PMVNF.When the smoking of cigarette 18 at the opening 8 and of two identical cigarettes is completed, the filter 10 is weighed again. From the weight thus determined, the initial weight of the filter 10 is subtracted to give the weight of the total particulate matter (TPM) deposited on the filter 10. Then the filter 10 is extracted with an extraction solvent, e.g. . propane-2-ol. The extract thus obtained was subjected to gas chromatographic analysis to determine the filtered 10 deposited amounts of nicotine and water. The sum of the thus-determined amounts of nicotine and water was subtracted from the gravimetric determined weight of the TPM deposited on the filter mentioned above to give the weight of the PMVNF deposited on the filter.

30 Den indre del af skorstenen 9 blev renset med et extraktionsopløsningsmiddel, f.eks. propan-2-ol. En del af den således fremkomne extrakt blev analyseret gaskromatografisk til bestemmelse af den mængde nicotin, der var afsat på de indre vægge af skorstenen 9. Den således bestemte 35 nicotinvægt blev adderet til vægten af den påfiltret 10 afsatte nicotin, og herved fremkom den samlede vægt af DK 172182 B1 21 sidestrømsnicotin hidrørende fra de tre cigaretter. Denne vægt blev divideret med 3, således at man herved kom frem til vægten af sidestrømsnicotin pr. cigaret.The inner part of the chimney 9 was purified with an extraction solvent, e.g. propan-2-ol. Part of the extract thus obtained was gas chromatographically analyzed to determine the amount of nicotine deposited on the inner walls of the chimney 9. The thus-determined nicotine weight was added to the weight of the filtered 10 deposited nicotine, thereby producing the total weight of DK 172182 B1 21 sidestream nicotine derived from the three cigarettes. This weight was divided by 3 so that the weight of the side stream nicotine per day was calculated. cigarette.

5 Den resterende del af den extrakt, der fremkom ved rensning af skorstenen 9, blev analyseret ved ultraviolet teknik, idet der som standard blev anvendt en del af den ovenfor omtalte extrakt hidrørende fra filtret 10, hvorved man kunne fastlægge mængden af PMVNF afsat på de in-10 dre vægge i skorstenen 9. Den således fastlagte vægt PMVNF blev adderet til vægten af PMVNF afsat på filtret 10, således at man herved fik den samlede vægt af side-strøms-PMVNF hidrørende fra 3 cigaretter. Denne vægt blev divideret med 3, hvorved man kom frem til vægten af side-15 strøms-PMVNF pr. cigaret.The residual portion of the extract obtained by chimney cleaning 9 was analyzed by ultraviolet technique, using as standard a portion of the above-mentioned extract derived from filter 10, to determine the amount of PMVNF deposited on the insert the walls of the chimney 9. The weight of PMVNF thus determined was added to the weight of PMVNF deposited on filter 10, thereby obtaining the total weight of side-stream PMVNF derived from 3 cigarettes. This weight was divided by 3 to give the weight of side-15 current PMVNF per minute. cigarette.

CO-udbyttet i sidestrømmen pr. cigaret blev bestemt ud fra data hidrørende fra analysatoren 17.CO yield in the side stream per cigarette was determined from data derived from analyzer 17.
